OEP roundtable: Measuring environmental outcomes and implementing EIP targets

Assessing progress against environmental ambitions 

A central theme of the discussion was the challenge of accurately assessing progress against environmental targets. While statutory targets and the EIP provide a long-term structure, participants noted that current progress remains uneven and, in many areas, insufficient to meet stated ambitions. 

There was recognition that reporting structures have improved in recent years, with greater attention being paid to delivery, governance and monitoring. However, participants highlighted that some policy areas still lack the detailed roadmaps, implementation frameworks and supporting strategies needed to drive meaningful progress. 

The importance of regular, transparent progress assessments was strongly emphasised. Clear reporting can help identify where interventions are succeeding, where progress is lagging, and where additional effort or policy reform is required. 

The challenge of measuring environmental outcomes 

Participants explored the wider challenge of measuring environmental outcomes in a robust and consistent way. Significant volumes of environmental data are collected across the UK, yet gaps remain in how this information is coordinated, shared and translated into evidence for decision-making. 

There was concern that despite substantial public and private investment in environmental programmes, there is often limited clarity on whether interventions are delivering intended outcomes. Better mechanisms are needed to evaluate impact, track progress over time and understand which policies are most effective. 

The loss of harmonised reporting systems previously available through European frameworks was also discussed. Participants noted that this has reduced opportunities for benchmarking, transparency and shared learning across jurisdictions. 

The importance of spatial data and local delivery 

A recurring theme was the need for stronger spatial data and place-based approaches. National statistics can provide an overall picture, but they often fail to capture local disparities in environmental condition, vulnerability or opportunity. 

Participants highlighted that more detailed spatial datasets could help target interventions more effectively, particularly in areas such as air quality, biodiversity recovery and land use planning. Better use of mapping and local evidence would allow resources to be directed where they can have the greatest impact. 

Local delivery is often constrained by patchy data quality, inconsistent methodologies and limited resourcing within local authorities and delivery bodies. Greater standardisation and investment in local capability were seen as critical to improving outcomes. 

Bridging the gap between national targets and practical action 

The roundtable also examined the challenge of translating national environmental targets into practical and enforceable actions on the ground. While high-level ambitions are clear, participants noted that mechanisms for filtering these targets into local planning, infrastructure and development decisions remain underdeveloped. 

There was strong support for more outcomes-based approaches that connect national priorities with site-level delivery. This could provide greater clarity for planners, developers, land managers and communities, helping to ensure that local decisions contribute directly to national environmental goals. 

Participants also stressed the importance of community priorities and bottom-up approaches. National policy must be capable of adapting to local circumstances, recognising that environmental improvement is often most effective when informed by place-based needs and local knowledge. 

Policy coherence and long-term certainty 

Policy consistency and coherence across government emerged as another major theme. Fragmented policy signals, changing incentives and inconsistent guidance can create uncertainty for organisations seeking to invest in long-term environmental outcomes. 

A more joined-up approach across departments was seen as essential, particularly in areas such as land use, farming, waste, planning and infrastructure. Participants noted that stronger alignment between environmental, economic and industrial strategies would help unlock progress at scale. 

Nature-friendly farming was highlighted as one of the most significant opportunities to deliver environmental gains, alongside the need for more predictable policy frameworks to build confidence among landowners, farmers and investors. 

Circular economy and tackling systemic drivers 

The discussion also considered the need to move towards addressing the systemic drivers of environmental degradation. Participants pointed to the role of production and consumption systems, resource efficiency and waste reduction in shaping long-term outcomes. 

Accelerating progress towards a circular economy was seen as a key opportunity. Stronger measures to increase reuse, repair, recycling and sustainable production could reduce environmental pressures while supporting economic resilience and innovation. 

Data sharing and transparency 

Participants emphasised the need for more open and accessible environmental data. While many datasets exist, they are often fragmented across institutions, difficult to access or not presented in formats that support practical use. 

Creating more transparent and interoperable systems would improve accountability, support innovation and enable stronger collaboration between government, business, local authorities and civil society. Better data sharing would also help identify successful approaches that can be replicated elsewhere. 

Looking ahead 

Overall, the roundtable highlighted both the scale of the challenge and the opportunity ahead. Environmental targets remain an important mechanism for driving progress, but achieving them will require stronger measurements, clearer lines of accountability and more effective links between national ambition and local delivery. 

A more integrated approach – combining robust data, spatial prioritisation, long-term policy certainty and cross-sector collaboration – will be essential if environmental commitments are to translate into real-world outcomes. 

ISEP will continue to convene stakeholders, support evidence-led discussion and contribute practical insights to help strengthen environmental delivery across the UK.
